Answers
Answer:
The pen will sell in 480 rupees
Answer: ₹360
Step-by-step explanation:
This is the case of a successive discount.
Always remember, in these cases, you can't add the discount percents and say that the shopkeeper is giving a 30% discount. Why? It is because the second discount is on the price we get after 1st discount.
Marked Price of the pen = ₹500
First Discount (in %) = 20%
Discount (in ₹) = 20% of ₹500 = 20/100 × ₹500 = ₹100
Price after 1st discount = ₹500 - ₹100 = ₹400
Now, the second discount of 10% is on this price, i.e., ₹400. That is the reason you can't add 20 and 10.
Price of the pen after 1st discount = ₹400
Second Discount (in %) = 10%
Discount (in ₹) = 10% of ₹400 = 10/100 × ₹400 = ₹40
Price after 2nd discount = ₹400 - ₹40 = ₹360
Therefore, the selling price of the pen is ₹360.
